Invoice finance costs in the UK usually combine a service or factoring fee with a discount charge on the money drawn. Your business may also pay setup, arrangement, maintenance, transfer, late-payment, or termination fees. The overall cost depends on the facility, customer quality, invoice terms, advance rate, and lender.
At Funding Bay, we help UK SMEs compare invoice finance facilities across our panel of over 200 UK lenders. Late payment is a persistent structural pressure on UK SMEs. The Small Business Commissioner reports that late payment costs the UK economy £11 billion each year and contributes to approximately 14,000 UK business closures annually, with around 1.5 million UK businesses affected. Invoice finance is one of the most direct working capital tools for closing that payment gap, which is why understanding the fee structure matters before you sign an agreement.
How invoice finance works
Invoice finance is short-term business funding that releases money tied up in unpaid invoices. Instead of waiting 30 to 90 days for your customers to pay, you can access part of the invoice value sooner.
The process usually works as follows:
- The lender checks your invoices, customers, trading history, and facility terms.
- You use the funds to cover wages, suppliers, tax, and other operating costs.
- Your customer pays the invoice.
- The lender releases the retained balance after deducting the agreed fees.
The total cost depends on whether the facility uses a fixed fee, a pay-per-invoice charge, a service fee based on turnover, a discount rate on drawn funds, or a combination of these structures.
The British Business Bank Small Business Finance Markets Report covers UK SME finance product use across the market. UK Finance publishes quarterly Invoice Finance and Asset Based Lending statistics covering the size and structure of the UK invoice finance market.
There are two main types of invoice finance:
- Invoice factoring: The lender manages customer collections and credit control.
- Invoice discounting: You keep control of customer collections while borrowing against your invoices.
Invoice factoring can cost more because the service includes collections and credit-control work. Invoice discounting can cost less when your business has an established credit-control team, and you want the arrangement to remain private.
| Invoice factoring | Invoice discounting | |
| Who chases payment | The lender | Your business |
| Client knows about the arrangement | Usually yes | Usually no if it is confidential |
| Administrative work for the business | Lower | Higher |
| Suitable for | Businesses that want to outsource collections | Businesses with internal credit-control resources |
| Typical contract length | 12–24 months | 12–24 months |
These ranges are indicative. A lender will price your facility according to debtor risk, invoice volume, sector, contract length, and the level of administration required.
The main costs
A factoring or invoice-discounting facility can include several separate charges. Your agreement should show which fees apply, what triggers them, and whether each fee is calculated on invoice value, drawn funds, turnover, or the facility limit.
| Charge | What it covers | Common pricing basis |
| Service or factoring fee | Administration, ledger management, and collections | Percentage of gross invoice value or turnover |
| Discount or interest charge | Use of the money advanced | Percentage of the amount drawn, often calculated daily |
| Arrangement or application fee | Credit assessment and facility setup | Fixed one-off amount |
| Due-diligence fee | Checks on the business and its customers | Fixed fee or included in setup costs |
| Maintenance or management fee | Ongoing account administration | Monthly fee or minimum monthly charge |
| Minimum-volume fee | Applies when the business does not use enough of the facility | Monthly or annual minimum |
| Bad-debt protection | Protection against an approved customer failing to pay | Percentage of invoice value |
| Bank-transfer fee | CHAPS or other payment processing | Fixed fee per transfer |
| Late-payment fee | Additional administration after missed payment | Fixed fee or percentage |
| Early-repayment fee | Ending or repaying the facility before the agreed term | Percentage of the balance or fixed amount |
| Termination fee | Closing the facility and reconciling the ledger | Fixed fee or contractual charge |
| Refactoring fee | Reassigning an invoice to the business | Fixed fee or percentage |
Service and factoring fees
The service fee pays for the administration attached to the facility. For factoring, it can include:
- Sales-ledger administration
- Customer statements
- Credit control
- Payment collection
- Account reporting
- Handling customer queries
A service fee is often charged as a percentage of the total invoices processed. Some lenders calculate it against turnover or apply a monthly minimum, so you can end up paying even when you draw little funding.
Discount and interest charges
The discount rate, also called an interest rate or on-the-money charge, applies to the amount drawn and the time it remains outstanding. It is separate from the service fee.
For example, a facility may charge the Bank of England Bank Rate plus a lender margin. A variable discount rate rises and falls when the base rate changes. A fixed-rate or pay-per-invoice structure produces more predictable costs, depending on the lender’s terms.
The Late Payment of Commercial Debts (Interest) Act 1998 gives UK businesses statutory rights to charge interest on late commercial payments, which some lenders reference when assessing debtor payment behaviour.
Setup, maintenance, and other charges
Before you sign, check whether the quoted price includes:
- Application and initial setup
- Annual review or renewal
- Monthly account management
- Minimum monthly charges
- Electronic or bank transfers
- Bad-debt protection
- Credit checks against your customers, verified through Companies House
- Legal documentation
- Early repayment
- Termination
- Late payment
- Broker or third-party charges
A low headline discount rate does not always produce the lowest total cost if the facility has high fixed fees or a monthly minimum.
A UK manufacturing case study
A UK manufacturing business based in the West Midlands, with £2.4 million turnover and 28 employees, secured a repeat contract with a national retailer worth £180,000 per month. The customer paid on 75-day payment terms.
The manufacturer faced a working capital ceiling. Monthly production costs of around £110,000 fell due before the customer settled, and a growing order book was pushing the payment gap wider each month.
We routed the manufacturer to an invoice discounting facility across the full sales ledger, structured on a confidential basis so customers were not notified of the arrangement. The lender agreed an 85% advance rate on approved invoices, a 0.6% service fee against turnover, and a 3.25% discount rate over the Bank of England Base Rate on drawn funds.
On a typical £180,000 monthly invoice, the manufacturer drew £153,000 within 24 hours of raising the invoice, paid a £1,080 service fee, and paid approximately £1,020 in discount charges over the 75-day payment period. Total facility cost per invoice: around £2,100, or 1.17% of invoice value.
The manufacturer covered production costs without disruption, took on two additional customers over the following six months, and grew turnover to £3.1 million without increasing overdraft use.
This example is illustrative. Actual advance rates, fees, and timing depend on the applicant, customer, invoice, and lender.
Factoring and discounting fees
Factoring and discounting use the same invoices as security, but the services and costs differ.
Invoice factoring
Factoring generally includes credit control and collections. The lender contacts your customers, issues statements, and monitors overdue invoices. The additional administration increases the service fee, but it reduces the workload for your business.
Factoring can suit your business if you:
- Have limited internal credit-control resources
- Want regular help with collections
- Prefer customers to know that a finance provider manages the ledger
- Need support monitoring debtor payments
Invoice discounting
Invoice discounting leaves credit control with you. You continue to invoice customers and chase payment. A confidential facility keeps the finance arrangement private.
Discounting can suit your business if you:
- Have reliable internal credit-control processes
- Want greater control over customer relationships
- Meet the lender’s confidentiality and reporting requirements
- Want to reduce the administration element of the facility
The cheapest option depends on the total fee structure. Discounting often has a lower service fee, while factoring can provide enough administrative value to justify its additional cost.
Which UK sectors use invoice finance most
Invoice finance suits UK businesses with B2B or B2G payment terms of 30 to 90 days. In practice, the product is used most heavily in five sectors, each with its own cost patterns.
UK recruitment and staffing agencies
They use invoice finance to fund the gap between weekly contractor payroll and end-client payment terms of 30 to 60 days. Costs tend to sit at the higher end of the invoice finance range because of contractor payroll volume and rapid drawdown patterns. Firms regulated by industry bodies such as the Recruitment and Employment Confederation commonly use whole-ledger factoring to outsource collections.
UK construction contractors and specialist trades
They use invoice finance to fund single project milestone invoices and whole-ledger arrangements. Payment terms of 60 to 90 days from Tier 1 main contractors, combined with retentions and staged applications for payment, make invoice finance attractive but complicate underwriting. Costs vary widely based on debtor concentration and retention structures.
UK professional services firms
These include consultancies, legal practices and accountancy firms. They use invoice finance for occasional large invoices that fall outside normal billing cycles. Firms regulated by the Solicitors Regulation Authority, the Institute of Chartered Accountants in England and Wales, the Association of Chartered Certified Accountants, or the Chartered Institute of Taxation tend to use selective or confidential invoice discounting rather than factoring, because client confidentiality matters.
UK manufacturing and engineering businesses
They use invoice finance to bridge production costs and customer payment on repeat contracts. Confidential invoice discounting is common when maintaining the customer relationship matters.
UK freight, logistics and haulage operators
They use invoice finance to bridge weekly fuel and driver costs against 60 to 90 day customer payment terms. Costs tend to sit in the middle of the invoice finance range.
For your specific sector, the right invoice finance product depends on the payment terms you offer, the number and concentration of your customers, and how much administrative support you want from the lender.
What affects the price
Lenders assess both your business and your invoices before setting a price. Factors include:
- The credit quality and payment history of your customers
- The number and concentration of your debtors
- Your average payment terms
- Your sector and type of goods or services
- Your annual turnover and invoice volume
- Your trading history and profitability
- Existing debts, disputes, or overdue invoices
- The advance rate you request
- Whether the facility is confidential
- Whether you need collections support
- The contract term and notice period
- Personal or business security requirements
- Whether bad-debt protection is included
Invoices from established commercial customers support better terms than invoices from customers with weak credit records or unpredictable payment patterns. Lenders verify customer creditworthiness through Companies House records and commercial credit references.
Comparing invoice finance with other borrowing
Invoice finance is designed for working capital linked to unpaid invoices. Other forms of borrowing may be cheaper or more suitable for a different need. Our secured vs unsecured business loans guide covers the differences between the main term loan structures in more detail.
| Funding type | Cost tendency | Security | Access speed | Suitable use |
| Invoice finance | Service fee plus discount charge | Eligible invoices | Usually faster than traditional lending | Ongoing working capital |
| Secured business loan | Often lower than unsecured borrowing | Business or personal assets | May take longer | Known capital requirement |
| Unsecured business loan | Usually higher than secured borrowing | May require a personal guarantee | Moderate | Fixed business investment |
| Overdraft or revolving facility | Interest on the amount used, plus possible fees | Depends on lender | Flexible once approved | Short-term or uneven cash flow |
| Asset finance | Depends on the asset, term, and deposit | The financed asset | Moderate | Vehicles, machinery, and equipment |
The cheapest way to borrow for your business depends on risk, available security, the term, and how often you need the funds. An established business with suitable assets can obtain a lower headline rate through secured borrowing. A business with strong invoices but limited security often finds invoice finance more practical. A revolving facility reduces interest when funds are used intermittently.
Questions to ask before signing
Before you accept an invoice finance facility, ask the provider to confirm:
- What percentage of each invoice will be advanced?
- Is the service fee charged on gross invoice value, turnover, or drawn funds?
- Is the discount charge calculated daily?
- Does the discount rate change with the Bank Rate?
- Is there a monthly minimum fee?
- Are setup, application, annual review, or renewal fees included?
- Are bank-transfer or drawdown charges applied?
- Does the price include credit control and collections?
- Is bad-debt protection available, and what exclusions apply?
- What happens when a customer disputes or does not pay an invoice?
- Can you repay early without a charge?
- What notice period and termination fee apply?
- Are broker, legal, valuation, or third-party fees payable?
- Is a personal guarantee or other security required?
- What is the estimated total cost at your expected turnover?
A written cost illustration should show the amount advanced, the retained balance, every applicable fee, and the estimated amount released after customer payment.
The Bottom Line
Invoice finance costs in the UK combine a service or factoring fee with a discount charge on drawn funds, plus a range of setup, maintenance, and event-triggered fees. The total cost depends on your customer quality, invoice terms, sector, and the specific lender you sign with.
The first practical step is to understand your working capital gap, gather your aged receivables report and last 12 months of business bank statements, and compare offers on a like-for-like basis using your actual invoice volume and payment terms.

When Finance Is Not the Answer
Borrowing is not always the correct path for your business. If your company is experiencing severe financial distress or structural insolvency, taking on more debt through invoice finance or any other product can worsen your position.
In these circumstances, we recommend seeking independent, professional advice. You can contact organisations such as Business Debtline or the Insolvency Service. You can also consult an SRA-regulated solicitor or an accountant regulated by ICAEW, ACCA or CIOT.
